Corrosion inhibitors in conversion coatings. III

The possibility to use metal corrosion inhibitors as effective components o f phosphating compounds for the purpose of enhancing the corrosion resistan ce of the resulting conversion coatings is analyzed. The influence of oxida nts and some complexing inhibitors on the formation and properties of phosp hate coatings is discussed. It is emphasized that ecologically harmful inhi bitors should be replaced by new inhibitors that meet both ecological and t echnological requirements.
